spring, we have ascertained facts which promise important measures 
for the control of this pest. Field experiments with remedies based 
on this new knowledge will be made this summer in the southern 
part of the State. 
(2) The life history of the corn plant louse. By tield obser- 
vations and office breeding experiments we have now cleared up the 
winter history of this species,—a point upon which nothing has 
heretofore been known. Similar methods will doubtless give us this 
season the data for a full life history of this pest of the corn fields. 
(3) The hfe history and species of various corn cutworms. 
By breeding experiments with the various cutworms affecting corn, 
we expect to determine the species of these larvee, and also the 
precise period when each ceases its destruction in the field,—a matter 
of economic interest, because it must fix the time when replanting 
corn destroyed by these insects will be profitable. 
(4) The life history of certain Tipulid larve, which have this 
year proved to be exceedingly mischievous in meadows and pastures. 
This subject has already been brought to satisfactory conclusion. 
(5) Field and laboratory experiments for the control of the 
ravages of the root web worm,—an insect recently discovered, which 
has this year done great and wide-spread injury to young corn. 
(6) Orchard experiments with lime for the prevention of 
damage to apples by the codling moth. 
(7) Field experiments in southern Illinois to test the influence 
of various fertilizers in supporting the farm crops against the attacks 
of the chinch bug. Other experiments for the protection of the corn 
crop against this insect will be begun this month. 
(8) Hlaborate studies of the contagious diseases of insects— 
especially of the silkworm, army worm, and the various cutworms, 
together with experiments for the artificial production of these dis- 
eases. 
(9) Studies of the animal life of the lakes of Illinois, for 
which we are systematically working over the large collections made 
while we were at Normal, and putting the data accumulated in shape 
for publication. 
(10) Of a different character are some personal studies of the 
minute anatomy of blind Crustacea as compared with those having 
the power of vision,—a study which we have here an unusual op- 
portunity to pursue, since these eyeless forms are very abundant in 
our subterranean waters. 
(11) Studies made by Professor Garman on the minute 
anatomy of peculiar forms of earthworms common in this region. 
(12) Collections and studies of a family of leaf mites (Phy- 
topti) injurious to vegetation, which Professor Garman is also carrv- 
ing forward. 
(13) Studies of certain families of parasitic Hymenoptera and 
of harvestmen (Phalangide), which Mr. Weed is making.
